Escape pipeline for Dongying tunnel construction

  Wuzhishan No
2 tunnel of Le Bai expressway is designed as a small clear distance two-way four lane tunnel, which is designed and constructed according to the medium and long tunnel, and is excavated in one direction from the exit
The left line of the tunnel is 399 meters long, the right line is 396 meters long, and the burial depth of Zui is 118 meters
The tunnel site belongs to the combined landform of karst peak clusters and tectonic denudation low mountains, gullies and valleys, and the terrain fluctuates greatly

During the construction process, Le Bai highway section 13, together with the headquarters, design and supervision units, continuously optimized the construction scheme, implemented dynamic design and construction, and ensured that each process was refined and targeted
The project department strengthened the process quality control, carried out the advance geological prediction and monitoring measurement work in a normal manner, and successfully overcome the construction problems of weak surrounding rock at the entrance, clusters of karst caves in the tunnel (the sizes of karst cavities are different, and large boulders in the cavity are mixed with mud, confined water, and liquidity), half soil and half stone, fault fracture zone and so on
The smooth connection of the tunnel provides valuable experience for the subsequent construction of the same type of tunnel in the project

In the case of tunnel collapse, the construction personnel can be evacuated in time and safely to ensure the personal safety of construction personnel
Therefore, the setting of tunnel escape pipe has great social and economic benefits
Nowadays, most of them are labeled with high molecular weight polyethylene escape pipes, which are sold at the price of ultra-high molecular weight

Basic parameters of escape pipeline:
1
Connection mode of escape pipeline: hoop connection and chain soft connection

2
Color: Orange
3
Weight: take dn800*30mm as an example, about 70kg/ M

4
Common specification of escape pipeline: dn800*30mm, the outer diameter of the pipeline is 800mm, and the wall thickness is 30mm

5
Length standard: 3 meters, 4 meters and 6 meters, which can also be customized according to requirements

Salient points of polymer escape pipeline:
1
The weight of the pipe is only 70 kg / m, and the weight of the same specification is only 1/8 of the weight of the steel pipe
Two people can install and disassemble it

2
The material cost of polymer escape pipe is low, which saves the procurement cost for engineering projects

3
Polymers have good corrosion resistance and can be recycled for 30-50 years

4
It still maintains good advantages under low temperature conditions

5
Polymer has high toughness and good impact strength

6
The design of pipe fittings is reasonable and easy to connect and disassemble

7
The inner wall of the polymer escape pipe is smooth
In the event of an accident, the safety escape speed is fast and it is not easy to cause secondary abrasion

Compared with traditional steel escape pipes, our UHMWPE escape pipes are light in weight, anti-oxidation, elastic, instantly deformed when impacted by strong external forces, absorb a large amount of impact energy, and then quickly restore their original shape
It is easy to install, and the tunnel escape pipe is connected by pipe hoop, which is more convenient to disassemble

Compared with high molecular weight polyethylene pipes, our new ultra-high molecular weight tunnel escape pipes have high pressure resistance, pressure bearing capacity and environmental damage resistance, which are far more than high molecular weight escape pipes, and can also be reused
Because the escape pipes are made of ultra-high molecular weight polyethylene materials, which have good aging resistance and slow embrittlement performance, the theoretical service life of the pipes is more than 100 years
